SPECIFICATION formingpart of Letters Patent No.m734,596, dated July 28, 1 90B.

Application filed May 29, 19053.V

To l1f/ZZ whom it may concern,.- Y

Be it known that LROBERT WILLIARD PAIN, a citizen of the United States, and a resident of the borough E Manhattan, city, county, and State of New York, have invented ce`r' tain new and useful Improvements in Music-l Rolls, of which thev following is a specification, accompanied by drawings.

This invention relates to music-rolls; and its object is to improve upon the means heretofore devised for locking themusic-roll to the rotating parts in a mechanical musical instrument.

To this end the invention consists ofa music-roll for carrying out'the above object and embodying the features of construction, combinations of elements, and arrangement fof parts havingthe general mode of operation substantially as hereinafter fully described and claimed in thisspecication and shown in the accompanying drawings, in which- Figure l is a side elevation, in longitudinal section, of a music-roll and the attachments therefor embodying this invention. Fig. 2 is a detail face view of one of the end washers for the apparatus. Fig. 3 is a transverse sectional View on the line a: of .the springplug shown in Fig. l to illustrate theshape of said plug. Fig. 4 is a longitudinal sectional view of the socket at one end of' the music-roll, the section through which Figfl: is taken being at right angles to the plane upon which the section of the plug as shown in Fig. lis taken. h

Referring to the drawings, A represents a portion of the frame of a musical instrument, in this instance uprights B being secured upon the portion ofthe frame A shown.- The shaft O is suitably supported in one of the.

uprights B, and any suitable means may be provided for rotar-ing said shaft, as shown the shaft being provided with a wheel or pul' ley D, and the music-roll is adaptedto be locked to the shaft and centered thereon in order thatit may rotate with the shaft. At

the other side of the frame suitable means are provided for revolubly supporting the other end of the roll.

According to this invention novel means are provided for locking the roll to the shaft C, one of these parts being provided with a slotted portion and the other with a pin Serial No. 159,253. (No model.)

adapted to said slotted portion, whereby the shaft and the roll may rotate together. The shaft C issupported in a suitable bracket E, having the apertured plug F, affording a bearing for the shaft, and the ange G, affording means for securing. the plug within the recessed portion of the upright B. The shaft C is suitably prevented from longitudiand set-screw I, adapted to be secu red upon the end of the'shaft outside of the bent portion J of the bracket E. As shown in this instance, the end of the shaft O is slotted, as at K, and the tongues L, formed by the slot, are tapered to substantiallya poi nt, as shown. The roll comprises the body portion O and the flanges P. Inside one flange is arranged a metallic socket Q, tapered inwardly to lit the taper ofthe tongues L on the shaft C, and extending across the'mouth of the socket is shown a pin R, adapted to enter the slot K in the end of the shaft O when the roll is placed in position upon said shaft. The socket Q may be suitably secured to the roll, as shown the neck of the socket being hollow, as at S, within which a suitable pin T may be fitted, which pin is embedded in the body portion of the roll. The construction shown affords provision for attachment of the flange P directly over the socket Q. When the socket Q is slipped over the tapering and slotted end of the shaft O, it will be .seen that the roll is locked to the shaft and the parts are easy ot' manipulation, because .the tapering end of the shaft readily slips into the socket Q, and is centered therein as it enters. The pin R readily slips into the slot K of the shaft without adjustment of the parts. I n

Suitable means, as stated,are provided for supporting the other end of the roll, as shown in this instance the upright B being provided .with an aperture within which the spring-pin a operates. This pin is provided with a rounded knob b at its end, which is adapted to enter the hollowed end of the plug c, shown embedded in the body portion O of the roll. The iiange P of the roll may be suitably'secured about the plug c. The spring-pijn at is provided with a collar d, between which and the outer washer e the coiled spring fis compressed. The outer end g of the pin projects through the aperture h in the washer e,

nal movement, as by means of the collar H while the other end of the pin projects through au aperture in the Washer 7l, so that the pin may be moved longitudinally against the tension of the spring to permit the insertion of the roll between the pin a and the shaft C. In order to prevent rotation of the pin d, one side of the same is attened, as atj, and the aperture h in the Washer e is provided with a at side 7c, so that the pin a will not rotate, although the roll will rotate upon the same.

According to this invention the roll may be readily slipped into place and as readily removed therefrom. The parts are simple and cheap in construction and are not liable to get out of order, nor may they be easily broken. The roll is perfectly centered and may be rotated at a high speed Without disarrangement of the parts.

This invention is not to be understood as being limited to a socket having a cross-pin therein, for any other locking means may be provided in the socket adapted to cooperate with the slotted portion of the shaft and lock the roll and shaft together, and While I have shown the slotted portion of the shaft as tapering the invention is not to be understood as-being limited to a tapering slotted portion.

Obviously some features of this invention may be used Without others, and the invention may be embodied in Widely varying forms.

Therefore Without limiting the invention to the construction shown and described nor enumerating equivalents, I claim, and desire to secure by Letters Patent, the following:

l. rlhe combination of a music-roll and a shaft, one being provided with a socket and the other with a slotted portion adapted to said socket, and the socket having locking means adapted to cooperate with the said slotted portion and lock the parts together, for substantially the purposes set forth.

2. The combination of a music-roll provided with a socket and a shaft having a slotted end adapted to the socket on the roll, and means provided in connection with said socket and adapted to cooperate With the slot in the end of the shaft for locking the shaft and roll together, for substantially the purposes set forth.

3. The combination of a music-roll and a shaft, one being provided With a tapering socket and the other with a tapering and slotted portion adapted to said socket, the socket also having a cross-pin adapted to coperate with the said slotted portion and lock the roll and shaft together, for substantially the purposes set forth.

4. 'lhecombination ofamusic-rollprovided with an inwardly-tapering socket and a shaft having an outwardly-tapering and slotted end adapted to said socket, the socket also having a cross-pin adapted to enter said slot in the end of the shaft and lock the shaft and roll together, for substantially the purposes set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

ROBERT WILLIARD PAIN.
